On my 32 year old H-16 has some beaching wear on the bottom. I can feel the weave but not the fabric. Build up sugestions needed, looking at the west sys epiglass with a filler sounds good. Can I add color to this?
Any advice would be well taken seems like one project turns into another wondering if I'll make summer much less spring

Each formulation of epoxy is different. I know that you can mix the West Marine gelcoat repair dye in with Lowe's epoxy but it may interfere with the curing of another kind. You'll just have to try it and see, but yes epoxy and high-density filler would be the way to go I think.
